The close relationship existing between the heat treatment and the magnetic properties of iron and steel, as well as between their heat treatment and mechanical properties is becoming recognised as very important. Changes in the physical properties resulting from thermal treatment generally indicate certain transformations and changes in structure, and have been studied in the case of 1% carbon steel, as a result of which it has been shown that a very rapid rise of the maximum and residual...

The author first presents a summary of previous methods of measuring the absolute reflecting powers of surfaces. Nutting's apparatus depended on the principle of infinite parallel planes, and was subject to various inaccuracies. Most of the other devices utilise the integrating sphere. Apparatus. - The new reflectometer devised by the author utilises a sphere with whitened interior, a portion of which can be removed and the surface to be examined substituted. A narrow beam of light can be...

The research deals with a cobalt-chrome steel of the following composition: C, 1.75%; Mn, 0.26%; Co, 2.90%; Cr, 15.0%. Samples were cooled from a constant temperature of about 900°C. at varying rates. As the rate of cooling is increased the temperature Ar' gradually falls from 770° to 700°, with a cooling rate of 0.7 deg. C. per sec. The lowered point Ar' makes its appearance at a cooling velocity of 0.15 deg. per sec., falling from 450° to 380° as the speed of quenching is increased to...
This paper deals with a method of guiding a ship or aeroplane by means of radio signals sent from a particular type of radio beacon. The crossed-coil antenna directive radio beacon consists of two coil antennae crossed at an angle of about 135 degrees with respect to each other, signals being transmitted alternately from each coil antenna. Waves are thus intermittently propagated directively from each coil, the intensity of the emitted wave with respect to the plane of each coil varying in...

It is pointed out that according to Nernst's equation the potential of the manganese peroxide electrode should be a logarithmic function of the hydrogen-ion concentration. Experiments were therefore made on manganese peroxide electrodes, using various kinds of ore, and their potential was measured in ammonium chloride solution with various hydrogen-ion concentrations. It was found that the law held in the case of mixtures of graphite and some manganese ores, but that the potential of similar...
